At PNNL, our researchers are unlocking fundamental discoveries in theory, chemistry, catalysis, subsurface science and artificial intelligence and transforming them into technological solutions for carbon capture, carbon utilization, and geologic carbon storage.
In support of the U.S. Department of Energy’s carbon management mission, PNNL collaborates with academic, governmental and industry partners across United States and around the world. Together, we are developing technologies to transition conventional fuels and processes toward a carbon-neutral energy future.
Through our research for DOE’s Basic Energy Sciences separations program, PNNL scientists are leading the development of the next generation of solvents for carbon capture. These solvents not only capture CO2, they are also more energy efficient and cost effective than existing commercial technologies. PNNL’s Carbon Capture program recently accomplished the lowest carbon capture costs to date at $39/tonne CO2, offering opportunities to reduce the Nation’s cost of achieving net zero emissions targets.
Through new discoveries about the CO2 reactivity in these solvents, PNNL experts in solvent chemistry and catalysis are leading the advent of a new field of integrated CO2 capture and conversion. In partnership with our colleagues in DOE-FE’s Carbon Utilization program, PNNL is exploring ways to improve the efficiency and cost-effectiveness of converting CO2 into valuable commodities while enabling decarbonization strategies.
PNNL has more than 50 years of expertise in subsurface injection, fate, and transport. We have partnered with DOE’s Office of Fossil Energy for decades to help achieve the office’s Carbon Storage mission of deep-decarbonization. This work includes:
- permitting and demonstrating the first mineralization of supercritical CO2 in basalt reservoirs (Wallula)
- siting and successfully developing the first Class VI permit ever granted (FutureGen 2.0)
- developing high-performance, computing-enabled, and real-time geophysical imaging and forecasting tools to support industry-driven, commercial-scale deployment of geologic CO2 storage under DOE’s new SMART Initiative.
